How do they catch speeders without radar guns?

**My personal guess is that they don’t even have dedicated units for this, and probably use the same police choppers they’d otherwise be using in emergency situations for this application. And they probably don’t do it very often. **

My experience is that helicopter-enforced highways are used at times when the state can hope to catch an inordinated number of speeders.

Each year at Spring Break time, Interstate 10 between the Alabama-Florida state line and Panama City, FL was fairly heavily patrolled by helicopters, or so it seemed (at least back in the early '90s. They busted spring-breakers left and right every year.

At other times of the year, the helicopters were nowhere to be found.

I’ve been trying to find a cite for this, but I’m afraid I just have what my friends told me. **

Thanks for trying, anyway. That’s still kind of an interesting idea - that there are some limitations to who can use them. Perhaps there is a reason similar to the one in PA that Knighted Vorpal Sword cites.
